. IMPROVEMENT IN MACHINES FOR BENDING SHEETWIETAL.

Specification forming part of Letters Patent No. 115,281, dated May 30 1871.

We,WILLrAM COOLEY and HENRY OOOLEY,

Improved Machine for Shaping the Sheets of Iron, Tin, or other material used out ofwhich eaves-troughs are to be made, of which the 3 *following is a specification Nature and Objects of at Invention.

, Our invention is a machine for shaping the i sheets of iron, tin, or other material used out of which eaves-troughs are to be made, and

consists in a frame, as represented in drawing,

with dies or molds, made as shown in drawing, the shape of the intended eaves-trough, the

length and strength being made to suit the material being used.

it I Description of the Accom mnying Drawing.

Figure I is an end View. Fig. II is a sec- General Description.

i We make the machine of iron or any other suitable material, each component part being formed to answer and perform the work re quired of it. A is the lower or stationary die or mold. .B is the movable die or mold, and

W11 is worked as we will describe further on. O is i a the flanging piece, and is worked by the lever I) being hinged at E. In the first place we should mention that the face or bottom. side of B is shaped to correspond with A, and the part M is intended to wire the material being b worked, as described further on. or die B, as we have before mentioned,is movable, and is attached to the main portion of The mold the machine bythewupright pieces F, which are formed so as to fit into and slide in the perpendicular pieces G. The pieces F are fastened tothe backor topof the die or mold B, 7 and the pieces G to the main machine. The

crank-shaft H binds the two pieces G together, and on one end of it is the crank-handle I.

Therods J are connected, as shown in drawing, to the pieces F and to the cranks on the crank-shaft H; consequently, the whole being connected, as described, upon *turnin g the CPttl]k1l2tIld16 I, the die or mold B rises and falls as required. The crank-handleK is connected to and works the flanges L, which runs parallel with M, the two being. so placed that, when the material being Worked is in the machine, upon turning the crank-handle K a wire edge is formed, as desired, the said flanger. L being attached to a spindle, which is not withdrawn, but is permanently attached to the body of the machine.

The operation is asfollows: Turn the crankhandle I so as to lift the die or mold B, which will leave a space between the two dies A and B. Place the sheet of tin or whatever you are about to shape in this space between the two dies. The workman will readily understand how to place it to allow for wiring, 870.,

i the sheet being, of course, a size which will correspond with the machine. Having placed the sheetbetween the dies, we now turn the crank-handle I, bringing the two dies A and B close, which will, of course, shape the sheet to their form. Having closedthe flanger G and turned the crank-handle K, which makes L close on M, forming a wire edge on the sheet, the shape of the eaves-trough is complete, and upon turning the crank-handles before mentioned, and making the flan ger 0 open out, the pressure is removed from the sheet, and it may be drawn out from the side of the machine. The process is repeated and every sheet formed alike. i

Claim.

We claim as our invention- The combination of the dies or molds A and B, the rods J, connected to the crank-shaft H, and turned by the crank-handle K, substantially as and for the purpose hereinbefore set forth.
